PORT CHARLOTTE, Fla. -- The Minnesota Twins announced Tuesday that Joel Zumaya's Tommy John surgery will be performed by Dr. James Andrews at a clinic in Pensacola, Fla. on March 29.

It's likely Zumaya's roster spot will remain idle until at least that date.

"I probably won't make (a roster decision) until I have to, which isn't now, of course," general manager Terry Ryan said prior to the Twins' game against the Rays. "Once you have to submit your 25-man roster, if you need (40-man) space, then we'll make a decision."

The Twins aren't forced to submit an official 25-man roster until just prior to their April 6 season opener in Baltimore.

Asked if the team had decided whether to place Zumaya on the 60-day DL or just release him, Ryan said, "We can do whatever we want."

Either way, the Twins will eventually have an open 40-man roster spot to play with. And there are several non-roster invites Ryan has his eye on, including shortstop Brian Dozier, third baseman Sean Burroughs, and right-handed reliever Jared Burton.

Dozier, by rule, doesn't have to be placed on the 40-man roster until after the 2012 season, but it's likely he will make his major league debut much sooner than that.

Ryan said Zumaya will likely take his rehab process to San Diego.

"He thought it out over about four or five days, so you know it didn't come lightly to him," Ryan said about Zumaya's decision to undergo surgery. "I think his age has a lot with wanting to go through the procedure, because he's only 28."
